Protein contains 0.5% glycine. What is the minimum molecular weight of this protein if M.m. of glycine = 75?

Protein contains 0.5% glycine. What is the minimum molecular weight of this protein if M.m. of glycine = 75? How many amino acid residues are in this protein?

Decision:
M.m = 75: 0.5 × 100% = 15000
15000: 100 = 150
Answer: 150 amino acids in this protein.
